Companies have a new way to determine the feasibility of on-site renewable energy, after the EPA launched a tool to test vacant and contaminated land for solar and wind energy potential.

The alternative energy “decision trees,” developed by the EPA and the US Department of Energy’s National Renewable Energy Laboratory (NREL), give landowners, communities and elected officials ways to evaluate sites for renewable energy potential from a logistical and economic standpoint, without the need for technical expertise.
